10 free (or almost free) things to do with kids in Boston this March.

March in Boston can be a tricky month to navigate. It’s cold for the beach, but getting too warm for sledding, and somehow the most expensive month for indoor entertainment. The good news is that there are plenty of free (or nearly free) things to do with kids in Boston this month. Here are some excellent activities the whole family will enjoy that won’t drain your wallet this month.
1. Boston Family Days – Free Museum Access

3. Arnold Arboretum – Spot Signs of Spring
Cost: FREE
March is when the Arnold Arboretum starts waking up. Take a family walk to spot the earliest spring blooms, returning birds, and budding trees. It’s 281 acres of free outdoor exploration and one of the best things to do with kids in Boston when you want fresh air without spending money.
Learning angle: Bring a notebook and have kids sketch what they observe. It’s hands-on science in action.
4. Charles River Esplanade Walk or Bike Ride
Cost: FREE (not including bike rental if you don’t have bikes)
The Esplanade is perfect for a March day when it’s too nice to be inside but too chilly for the playground. Walk, bike, or scooter along the river. Playgrounds dot the path when kids want to take a quick break. This is truly an activity that will last all day!
Parent bonus: Grab coffee at nearby Tatte Bakery & Cafe!
5. Free Thursdays at the ICA
Cost: FREE
When: Every Thursday, 5-9pm
The Institute of Contemporary Art offers free admission every Thursday evening. It’s a great option for families with older kids interested in modern art.
Why evenings work: Less crowded than weekend days, and it feels like a special outing.
6. Castle Island and Fort Independence
Cost: FREE
Walk around Castle Island, explore the historic fort (tours available seasonally), and watch planes take off from Logan Airport. Bring binoculars for plane spotting!
Food tip: Grab takeout from Sullivan’s and have a picnic if the weather cooperates.
7. Harvard Museum of Natural History
